The writer suggests that people don't think through the benefits of technology, but I also believe we don't think through the costs of technology. Seemingly simple technologies end up coming with unique, and somewhat unforeseeable, unintended consequences. There are social consequences to each advance in narrow-casting, focused marketing, social networking, etc. There are environmental impacts for every kind of energy generation and transportation. We just don't know what they are in advance, in detail. We certainly don't think them through too thoroughly.

So, the question of whether the pendulum is too far towards imagining the benefits or imagining the problems is really open to interpretation. Some people think (about some things) that the precautionary principle should apply - but they didn't apply it to social changes like aspects of feminism, oddly enough, or to technological changes in birth control, even though these have direct impacts on human health and welfare. There are biases at work here, below the level of simply liking or disliking science.

But our friendly author appears to be too much of a Crusader to acknowlege them.
